Assessing the effect of prophylactic ankle taping on ankle and knee biomechanics during landing tasks in healthy individuals: A cross-sectional observational study.
Sao Paulo Med J
August 2023
Article Synopsis
- Current research shows that ankle taping (AT) effectively prevents injuries in athletes, but this study explores its effects on balance and knee alignment in healthy individuals.
- Conducted at the Universidad Europea de Madrid, the study involved 39 participants who tested their movements while taped and untaped, measuring outcomes like ankle range of motion and knee valgus during jumps.
- Results indicated that while AT restricted ankle movement and worsened knee alignment during jumps, it also decreased balance performance, suggesting that taping could increase injury risks and isn't advisable for healthy individuals.
